GTA 5 promotional art: Hidden clues or just art?

So Rockstar released some very impressive GTA 5 promotional art, featuring quad bikes, dogs and sunglasses! Can you believe it? Sunglasses. While to me these are just pieces of artwork, many are looking for hidden clues in them. Anything hinting at anything. Seems GTA fans are starved and desperate for some GTA action.

So here’s the art and here’s what I’ve gotten out of them.

Man on quad bike – There may or may not be quad bike riding Yugoslavian nerds with giant guns in the game.

Man with dog – Apparently you need a dog named chop and a bat to scare the crap out of people, or… it could just be one of your future enemies, in which case: RUN SON!

Sunglasses – I honestly don’t have a clue what’s reflecting in this chick’s sunglasses, but if I had to guess. I’d say it was a Minecraft version of the main character.
